Nashville, TN (SportsNetwork.com) - Jerron Seymour scored on a 13-yard run to cap a 17-point fourth quarter, as Vanderbilt rallied to claim a 31-27 upset of 15th-ranked Georgia.

Vanderbilt took advantage of three huge Georgia mistakes in the second half to fuel the comeback, earning its first win over a ranked team since 2008 against Auburn.

The Commodores (4-3, 1-3 SEC) had lost 17 straight games to ranked opposition and also snapped a 10-game home losing streak to Georgia, beating the Bulldogs at Vanderbilt Stadium for the first time since a 27-25 triumph in 1991.

Georgia (4-3, 3-2) was coming off a 41-26 home loss against Missouri last week and has dropped two straight conference games for the first time since the 2010 season.

The Bulldogs held a 27-14 advantage late in the third, but a muffed punt gave Vandy the ball in scoring position. A fourth-down personal foul penalty against Georgia then gave the Commodores a first down at the 15 and backup quarterback Patton Robinette scored from the two with 10:38 remaining to make it a one-score game.

Georgia failed to pick up a first down on its next series and Vanderbilt drove to the 10-yard line. Robinette, though, took a sack and the Commodores had to settle for a 40-yard field goal from Carey Spear to pull within 27-24 with just 4:44 to play.

The Vanderbilt defense made Franklin's decision to kick the field goal a good one by holding the Bulldogs without a first down again, and punter Collin Barber could not handle a high snap. He fell on the ball at his own 13 and the Commodores wasted no time taking the lead when Seymour scored on the next play with 2:53 left.

Georgia had plenty of time with the SEC's all-time yardage leader Aaron Murray leading the offense, but he had struggled all day and another mistake sealed the Bulldogs' fate. Brendan Douglas fumbled after a catch with 1:59 to play and Vanderbilt ran off all but the last few seconds.

Murray, who was intercepted on the game's final play, finished just 16-of-28 for 114 yards without a touchdown. He did run for a pair of Georgia scores.

"They played extremely well today. You got to give them a lot of credit," said Murray. "They did a great job of their scheme and we just didn't make the plays."

Vanderbilt lost quarterback Austyn Carta-Samuels in the second quarter when he was sacked by Jordan Jenkins. Carta-Samuels, on crutches on the sideline in the second half, had thrown for 111 yards on 12-of-20 passing before leaving the contest.

Robinette took over and connected on 9-of-15 throws for 107 yards. Seymour finished with 75 yards rushing and two touchdowns.

Georgia opened the scoring with a 22-yard Marshall Morgan field goal on its opening possession, but Vanderbilt responded with a 76-yard march for a touchdown, taking a 7-3 edge on Seymour's 4-yard run. The Bulldogs regained the lead on Murray's 1-yard TD run on the final play of the first quarter.

Vanderbilt started the second quarter with a lengthy drive that stalled at the Georgia three. The Commodores set up for a short field goal, but kicker Spear took a handoff from holder Taylor Hudson and had virtually no resistance on his way to the end zone to give his team a 14-10 lead.

"The fake field goal was an important play in the game," said Franklin. "We have to take calculated risks."

After a trade of punts, Shaq Wiggins jumped a bubble screen and raced 39 yards untouched with the interception of Carta-Samuels for a touchdown with 6:24 remaining in the half to put Georgia in front.

The Bulldogs got the ball back after Carta-Samuels left the game on the ensuing Vanderbilt possession and marched inside the Commodores five. Murray, after a first down inside the one was overturned on replay, rolled out to the right and had an open lane to the end zone for the 2-yard score and a 24-14 lead in the final minute of the half.

Georgia extended its advantage on a 23-yard Morgan field goal with 6:24 left in the third, then snuffed out a potential Vanderbilt scoring drive when Corey Moore picked off a deflected Robinette pass at the Bulldogs' 35.
